java - store.connect(host,username,password) 未连接到我的 gmail

Question

我正在尝试编写一个连接到 I MAP g 邮件收件箱并从收件箱中检索所有邮件并处理它们的测试用例但是语句 store.connect( host, userName, password ) ;未连接到 g 邮件存储。当我跟踪调试输出时没有收到错误，如下所示

DEBUG: setDebug: JavaMail version 1.4.6
DEBUG: getProvider() returning javax.mail.Provider[STORE,imaps,com.sun.mail.imap.IMAPSSLStore,Oracle]
DEBUG IMAPS: mail.imap.fetchsize: 16384
DEBUG IMAPS: mail.imap.ignorebodystructuresize: false
DEBUG IMAPS: mail.imap.statuscachetimeout: 1000

DEBUG IMAPS: mail.imap.minidletime: 10
DEBUG IMAPS: enable STARTTLS
DEBUG IMAPS: trying to connect to host "imap.gmail.com", port 993, isSSL true 

我用下面的代码解决了这个问题。

MailSSLSocketFactory socketFactory= new MailSSLSocketFactory();
        socketFactory.setTrustAllHosts(true);
        properties.put("mail.imaps.ssl.socketFactory", socketFactory);
.........
Session session = Session.getDefaultInstance(properties);
